The present invention relates to aroma chemical compositions containing 3,5-diethyl-2-propyl-tetrahydropyran, a 3,5-diethyl-2-propyl-dihydropyran or a 3,5-diethyl-2-propyl-pyran, a mixture of such compounds, a stereoisomer of one of these compounds, or a mixture of stereoisomers of one or more of these compounds. The invention further relates to a method for preparing such compounds, stereoisomers or mixtures thereof, to the composition obtainable by this method, to the use of such compounds as an aroma chemical or for modifying the scent character of a fragranced composition; and to a method for preparing a fragranced composition or for modifying the scent character of a fragranced composition using said compounds. Moreover, the invention relates to 3,5-diethyl-2-propyl-tetrahydropyran, to its stereoisomers and to mixtures of these stereoisomers.

Aroma chemical compositions containing 3,5-diethyl-2-propyl-tetrahydropyran and/or unsaturated derivatives thereof

The present invention relates to a two-stage hydroformylation process for producing pound of the formula (I) and to a process for producing a compound of the formula (V) comprising the two-stage hydroformylation process for producing a compound of the formula (I) followed by hydrogenation of the compound of the formula (I). 

Hydroformylation process for producing 1,6-hexanediol derivatives

The present invention relates to the use of diesters of 2,5-dimethyl-2-hexenedioic acid, 2,5-dimethyl-3-hexenedioic acid and 2,5-dimethyladipic acid or a mixture thereof as a fragrance or as flavor, to a method for imparting or modifying a scent or a flavor to a composition by including said compounds into such composition, to a fragrance containing composition and/or a fragrance material containing said compounds and to a process for preparing diesters of 2,5-dimethyladipic acid.

Aroma chemicals

A process for decomposing formates in formate-containing compositions of matter comprises reacting formate-containing compositions of matter in the presence of at least one heterogeneous catalyst comprising lanthanum and at a temperature of from 80 to 180&#xb0; C. and a pressure of from 0.1 to 60 bar, the formate-containing compositions of matter having a pH of from 6.5 to 10.

Method for breakdown of formates

Cured epoxy resins are widespread on account of their outstanding mechanical and chemical properties. It is common to use epoxy resins based on bisphenol A diglycidyl ether or bisphenol F diglycidyl ether, but for many sectors these are problematic because of their endocrine effect. The present invention relates to 2-phenyl-1,3-propanediol diglycidyl ether derivates and to curable epoxy resin compositions based thereon, as alternatives to the bisphenol A or bisphenol F diglycidyl ethers and to the epoxy resin compositions based thereon.
